Hi . Thank you for asking your question on JustAnswer. so its running at 210?is it pushing out coolant or anything?
240 is too high..sounds like ya may have head gasaket failure... 198 to 210 is fine 240 is pushing the limits
very uncommon for failure but possible....any coolant loss?
is the coolant temp sensor accurate?
that would not explain it only spinning on the shaft when towing...but next step is to pull the water pump and check...
180-195 is normal 210 when pulling a load...anything over 220 would be considered over heat
start by cleaning the coolant stack a mouth piece upgrade also helps we also have had bad luck with stant and aftermarket tstats try running a ac delco
pull the water pump and check the impeller then...i had a rash of bad stant t stat on llys it almost drove me crazy at one point
yes where they have a slow internal leak...and they are not pushing exhaust into the cooling sstem ..not common but it happens
if it runs at 210 thats considered normal operating range..if it stays under 220 u should be fine
